Replacing the Averatec 3120V CPU FanRecently, my Averatec 3120V notebook crashed. At first, I had thought it was the hard drive crash. But after replacing the hard drive, the computer made a loud grinding noise on boot up. This problem made me look at the CPU fan. The fan is usually the first component to go in a computer system. Being in constant motion, it's only a matter of time before the rotational bearing wears out. So periodically replacing the fan in a computer is pretty much without a doubt. However, this is a notebook computer we are talking about. Question is how hard is it to source a fan? Before we can source a fan, we need to find out what fan it is. And we can only do that by disassembly the CPU compartment. First thing to do is to look at the bottom of the notebook and find all the component covers. On the Averatec 3120V notebook, you can easily spot the CPU and fan cover by the circular vents (see photo below). Attached Image: Chieh Cheng On this notebook, we can only pry open the CPU/fan cover after removing the memory cover. There are two small screws that can be easily removed with a Phillips mini-screwdriver. Remove these screws to reveal the memory module (see photo below). Attached Image: Chieh Cheng Once the memory upgrade cover is removed, the CPU/fan cover can be pried open. Insert mini-flat-blade screwdriver into the slot between the CPU/fan cover and the memory upgrade opening to pry the panel open. After removing the cover, the CPU fan and heat sink is exposed as shown in the photo below. Attached Image: Chieh Cheng To remove the fan on the heatsink, use the mini-Phillips screwdriver to unscrew the three larger screws on the heatsink. These three screws are under spring tension. So you have to take turns unscrew them repeatively until they are all Attached Image: Chieh Cheng The following photo shows the underside of the fan and the heatsink. Attached Image: Chieh Cheng The following photo shows the fan label with the manufacturer and model number. It's a Sunon 054010VH-8. A quick search on Google showed that Allied Eletronics sells this fan for $18.27. I just put in an order. I will keep you posted on the result when the fan arrives. Attached Image: Chieh Cheng I got the new fan yesterday. Looks just like the old one. The label is slightly different "MagLev System" rather than fully spelled out is what stood out the most. The fan is easy to replace once you have the heat sink out. Just unscrew three screws, swap the fan, and screw the three screws back. Putting the heat sink back is like taking it out. The screws are under tension, so you have to screw each of them a little bit at a time in turn, until they are all tight. Other than that putting everything back is just the reverse of taking it apart. Chieh Cheng Thanks for all the information. I've been looking online for two hours for a place to purchase a new fan. Your link was very helpful....Thanks! AJ Hey nice job with the installation guide it will help many people. Thanks for the post and the link. Shane I can not use my laptop to my fan does not work, so I wanted to buy a Fan, please give me the price please . Besy Wilson Attached Image: Besy Wilson Thanks for this - I had a problem with my fan stopping and decided to go through these steps to check it out. Very easy to get to the CPU on this notebook! Clearly they planned for failure :-) Just to see what I was dealing with, I pulled off the labels on the 2 faces of the fan. Not much interesting on the label side with the writing, but on the pure black label (didn't even realize it was a sticker at first)...when the label is peeled back it appears to partially expose ball bearings (3 holes with metal visible). I tried some 3 in 1 oil on this side, worked it for awhile, and it came back to life. Very stiff to turn when it first came out, but now is very smooth. I left this exposed, but I should probably put some tape on it to keep dust out. Not sure how much life it has, but it seems like new for the time being. I'd definitely try this before replacing the fan. Also, you don't need to remove the heatsink to do it if you don't want to - just make sure to dry up excess oil before turning it on! pat That's a great idea, pat. I still have my old fan. Maybe I'll try lubricating it the next time. Or I'll build it into something else. Thanks. Chieh Cheng Thanks for keeping this post up. I just pulled my old 3120v out to be a living room email machine and found it needed a fan. It's on order! BigA I removed the fan from my Averatec laptop, few times and cleaned it up but this last time I have problem to connect it to motherboard seems the connection doesn't exist anymore or it is broken!! How can I repaire this? momken Hey where could I buy that guys can you give me a link to a site. lloyd randolph ancheta note: Sunon has replaced this part and modified number; 054010VH-8 SKU: MS.V1.M.B245; B245 is now B24.
